One of the objects ofthe invention isr to provQvide improved construction for protecting the internal brake and the brake iiange might lie-discharged or the axle housing. Aiiothernobject is to so forni thel construction thatjthe brake drum is reinforced. Further objects ofl the invention reside in the novel features of constriiction and coinbinations and arrangements of parts as more fully'lierei-nafter set forth; f

The ring 16 is firmly secured to the annular flange 19A as by being teleseoped tliereover and formed with bosses 2O for engaging corresponding depressions 21 formed in the annular flange; 'The rear end of the ring extends rearwardly beyond the rear end of the hub and terminates in a rearwardly and inwardly inclined flange.

The arrangement is suchthat any lubricant discharged from the hub' or from a point adjacent the rear end of the hubk is intercepted by the oil collecting ring 16 and passes outside the brake drum through the grooves formed between the web of the brake drum and thewhe'el hub, centrifugal force resulting from rotation 'of the cant. lliu'rthermore, by reason of the hollow ribs which are' preferably formed by pressis reinforced. y

In the modified `construction shown" in Figures and 6, 22 is thev wheel lhubhaving l ae. 24 are the wooden spokes having their inner beveled ends forming'the hub section 25. 2 6 is the rim `a't they outer ends of being in the form of the spokes,- this rim I a' `ielly for carrying the demountable tire carrying rim 27. 28 isl the brake drum havir'igy the web 29 'and the brake flange 30, the latter being adapted brake.` 31 are bolts and the spokes to the hub, the bolts extending through the web 29, the hub section and the fixed flange 23. f

In this constrnctiontlie portion of the brake ydrum web lying adjacent to the hub section 25 isalso provided with the out wardly extending or radial hollow ribs 33 form grooves in thev rontface of the web. The inner edgefof the web has the annular flange 34 which is also provided with peripherally rspaced hollow ribs extending Parallel t@ 'the 0f then/heel and fermby pressing and which ing grooves communicating with the grooves Y formed by the hollow ribs 33., The inner edge of the brake drum web terminates in the annular flange 35 which extends rear- Y hollow metallic tubes 36 within thepassages vin its front face flange,

formed between the hub section 25 and the adjacent portion ofy the brake drumweb 29.

What I claim as my invention is: A1. In a vehicle wheel, the combination with av hub and hub flange, of a brake drum secured to said hubflange and formed with a passage vextending outwardly toward the louter'periphervof'the wheel, and means uponsaidbralre drum for collectingr lubri-y cant discharged from lsaid hubfand conducting vthe lubricant to the passage.

f 2. In aj vehicle wheel, the combination with a hub and hub-flange, of a brake'drum provided with a passage extending outwardly toward the periphery of the wheel, means for securing said brake drum to said hub flange, and means upon said brake drum independent of said brake drum securing means for collecting lubricant ydischarged from said hub and conducting the lubricant to the passage. v 1
